[MSNoise] customizing plot problem

Dear MSNoise users, I want to use the customizing plot. So, I copied the dvv.py script to my project directory, then I edited the "from ..api import * to from msnoise.api import *". When I run the dvv code I faced the following error. I will be grateful for any help you can provide. Traceback (most recent call last): File "/home/user/testtt/dvv.py", line 189, in <module> main() File "/home/user/testtt/dvv.py", line 87, in main mov_stack, comp, '%s.txt' % current) TypeError: %i format: a number is required, not NoneType [Finished in 1.162s] All the best, Navid
